The present invention comprises a plurality of exciters that output sound in a prescribed frequency range and a plurality of piezoelectric speakers that output sound in a higher frequency range than the exciters. The plurality of exciters and the plurality of piezoelectric speakers are both located in a space between the outer panel and the interior material of the vehicle body or on an inner surface side of the interior material. The internal material conveys vibrations generated by each of the exciter and the piezoelectric speaker. The crossover frequency is present on the high-domain side of the output range of the exciter and the low-domain side of the output range of the piezoelectric speaker.

    本发明包括多个在规定频率范围内输出声音的激励器和多个在比激励器高的频率范围内输出声音的压电扬声器。多个激励器和多个压电扬声器均位于外板和车身内部材料之间的空间中,或位于内部材料的内表面侧。内部材料传送由激励器和压电扬声器中的每一个产生的振动。交叉频率存在于激励器的输出范围的高域侧和压电扬声器的输出范围的低域侧。
